How does Virginia Mason - Benaroya Research Institute compare with other laboratory buildings in Seattle?
The latest disclosures cover 32 laboratory buildings in Seattle, out of 3,871 buildings citywide. Its site EUI of 142.6 kBtu/ft² is about 20% below the average of 178.6 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 2.1 kgCO₂e/ft² is about half of the group average of 4.6 kgCO₂e/ft².
At 206,950 sq ft, it is roughly in line with the average floor area of 202,547 sq ft for those buildings. It was built in 1999, 13 years later than the group's average year built (1986). Across all 24 jurisdictions BuildingCensus covers, the 795 laboratory buildings average an ENERGY STAR score of 29 and a site EUI of 231.7 kBtu/ft².
How has Virginia Mason - Benaroya Research Institute's energy performance changed over time?
BuildingCensus holds 11 Seattle disclosures for Virginia Mason - Benaroya Research Institute, covering report years 2015–2025. Site EUI moved from 94.9 kBtu/ft² (2015) to 142.6 kBtu/ft² (2025), an 50% increase. Reported emissions went from 233 tCO₂e to 235 tCO₂e over the same span (up 1%).
What does a site EUI of 142.6 kBtu/ft² mean?
Site energy-use intensity (EUI) is the energy a building uses on site in a year divided by its floor area, in thousand Btu per square foot — lower is more efficient. Virginia Mason - Benaroya Research Institute's 142.6 kBtu/ft² across 206,950 sq ft works out to about 29.5 billion Btu (8,649 MWh-equivalent) in 2025. Its source EUI of 371.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 4,015,638 kWh of electricity for the year.
Which law requires Virginia Mason - Benaroya Research Institute to report its energy use?
Virginia Mason - Benaroya Research Institute reports under the Seattle Energy Benchmarking Ordinance (SMC 22.920), the legal basis of Seattle's Building Energy Benchmarking program, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2025 disclosure (source record seattle:434:2025). Seattle's Building Emissions Performance Standard (adopted 2023) applies to buildings over 20,000 sq ft: benchmarking verification is due 2027–2030 and initial emissions targets 2031–2035, reaching net zero by 2041–2050, with fines for non-compliance.
